a)the yard now
b)are playing
c)is playing
c)plays​

Answer 1

Thomas and Patrick ARE PLAYING outside.

Ou seja, letra B)

Are ao invés de Is porque Thomas and Patrick seria They (Eles), e seguindo a regra, THEY are, uma vez que is apenas se usa para he, she e it.

Espero ter ajudado, bons estudos :)
